Embodiment 1

[0060] The invention provides a light-curing filter element, which includes an adsorption material, a coating material, a light-curing glue and an auxiliary agent. The inside of the coating material is filled with the absorption material, and the outside of the coating material is placed with light at a set interval. Curing glue; or use non-impregnated and impregnated light-curing glue to mix and spin the covering material; or light-curing glue is filled between the adsorption materials; or light-curing glue penetrates the adsorption material and connects with the surface of the covering material; Or the light-curing glue is pasted on the side of the coating material; or the above two or more combinations; the auxiliary agent is added to the adsorption material or coated on the outside of the light-curing glue. figure 2 It is the SEM picture of the cured glue on the side of the light-cured filter element of the present invention.

Embodiment 2

[0087] Such as figure 1 As shown, the present invention also provides a method for manufacturing a light-cured filter element, including: putting light-curable glue into the adsorption material, coating material, and auxiliary agent; Mold to obtain the desired photocurable filter element.

[0088] The process of placing the light-curing glue is as follows: extrude the tank and inject the light-curing glue into the light-transmitting film of the auxiliary agent, and seal the film in sections to form a paste (such as figure 1 In device 1), the paddles are placed in the adsorption material and the coating material in a set arrangement (such as figure 1 device 2); or the light-curing adhesive is directly placed in the adsorption material, coating material, and auxiliary agent in the form of a 3-15 Pa·s high-viscosity liquid.

[0089] Wherein, the extrusion flow rate is 2-200 mm / s, preferably, the flow rate is 10-40 mm / s. Select the appropriate flow rate according to the materia...

Abstract

The invention discloses a photocuring filter element, which comprises an adsorption material, a coating material, a photocuring adhesive and an auxiliary agent, the adsorption material is placed in the inner side of the coating material, and the photocuring adhesive is placed in the outer side or the inner side of the coating material at a set interval; and the auxiliary agent is added into the adsorption material or is coated outside the photo-curing adhesive. The invention also discloses a preparation method of the photocuring filter element. The preparation method comprises the following steps: putting the photocuring adhesive into the adsorption material, the coating material and the auxiliary agent; performing soft forming; fixing by using a tool and carrying out photocuring hard forming at the same time; and demolding to obtain the required photocuring filter element. On the basis of adopting a fine filter material, a photocuring material is introduced and arranged in the basic filter material in sequence, and through two steps of soft forming and hard forming, preparation of the filter unit which is high in precision, high in strength, easy to form, low in pressure loss, low in rejection rate, high in universality and capable of reducing labor time and solid waste can be achieved.

Description

technical field [0001] The invention relates to a light curing filter element and a preparation method thereof. Background technique [0002] In the operating environments of semiconductors, liquid crystal panels, photovoltaic industries, air conditioning boxes, operating rooms, and pharmaceutical companies, there are many gas pollutants that need to be treated, such as organic gases, microbial pollutants, dust particles, oil mist, etc. For the above pollutants, the air filter is updated iteratively to meet the precise requirements. With the gradual improvement of our country's environmental protection requirements, the filtration accuracy requirements of air purification filters have also increased, and the fineness of the selected filter materials has been increased to achieve higher efficiency and life goals. However, reducing the particle size of the filter material has problems such as low filter material strength, local collapse, and high scrap rate. [0003] The car...
